Background

Tera, like most members of the group, was trained to lose his emotions to better undertake his missions. As the Root members each uses a codename, it is unknown what Tera's real name is, if Tera even has one. Even though the organisation has been officially disbanded, Tera remains loyal to its head, Danzō Shimura.
